Stability tests for time-delay systems: MATLAB code
Let consider a
time-delay system of the form:
where
x(t) is the state vector (dimension n), A and Ad are constant matrices.
h is the delay. Depending on the nature of the delay and informations
you have, different stability conditions may be tested. Some MATLAB
codes are listed below:
- in the case where h is time-varying, belongs to [0 , hmax] and with a bounded derivative |dh/dt|<d, matlab-function: ddstab_tvds(A,Ad,hmax,d,mysolver);download.
- in the case where h is time-varyin, belongs to [hmin , hmax] and with a bounded derivative |dh/dt|<d, matlab-function: drstab_tvds(A,Ad,hmin,hmax,d,mysolver);download.
